JOHN HANCQ, OF JAMESTOXVN, NE YORK.

To all w/zdm, it may concer/r:

Be it known that I, JOHN HANCQ, a citi zen of the United States, residing at the city of Jamestown, in the county of Chautauqua and State of New- York, havel inyented cer tain new and-useful Improvements in Electric 'Varp Stop-Motions, of which the following, taken in Connection with the accompanying drawings, is a specification.

The invention relates to elect-ric warp controllingdevices for looms and isan improvementA upon the warp stop motion shown in application of the applicant filed April 15, 1919, Serial No. 690,712; and the object of the present improvement.v is tosimplify and render more etlicient the former construction of the applicant; and to these ends the invention comprises the novel features hereinafter set forth and claimed.

In the drawings, Figure 1 is an elevation of a heddle frame with the heddles in position, the middle portionl of the frame beingr broken away and showing the electrical conr nection whereby the electrical circuit is altornately made and broken with the rise and fall of the frame in the loom; thc frame' bcingshown in the lowered position thereby completing t-he electrical Circuit. Fig. 2 is Va sectionatview of the frame at line X X in Fig. 1, showing t-he'heddle as it, is normally 'supported on the thread and not resting upon the electrical Contact, that with the l frame in the lowered posit-ion; and Fig. 13 is a similar view with the heddle resting= upon the Contactv strip and the thread broken; Fig. 4 is an elevation of a portion of the end of the hcddle frame with the elec tric connection disconnected or with frame in thc raised position. Fig. 5 is a perspective View of the electrical contact pins with the parts in the closed position when the frame is lowered; and Fig. G is a similar view with the parts in the open or disconnected position when the frame is raised. Fig. 7 is a sectional view of the con tact strip and supporting flange on the under edge of the' top cross rail of the trame. Fig. 8is an end elevation of the loom with the electrical warp stop motion attached thereto.'q Fig. t) is a detail elevation of the magnetic tripping nie-ans for operating` the stoppingt mechanism of the loom, the tripv ping mechanism beingshown in the normal position with unbroken threads; and Fig.

Application filed November 25, 1912. Serial No. 733,256.

10y is a similar View showing the act-ion of the magnet when the thread breaks-intrip.

ping the stopping mechanism of tl-ieloom; and Fig. 11 is a plan view of said tripping#- mechanism. Fig. 12 is a sectional view at; line Y Y in Fig. 11, showing the relationfof the parts. ,Fig 13 is a sectional View at line ZZ in Fig. 9. Fig. 14 is a detail elevation of the tripping plate removed fronr the other mechanism.

Like numerals of reference refer to corresponding parts in the several \"iews.

The numeral ZOdesignates the'looin-.fraine upon which the heddle frames 21 are supported in the usual manner. lThe heddle frames 21 comprise the top crossrails 22 and the bottom cross rails 23 which are connected by the end pieces "lat and 25. The heddle frame 21 is, preferably made offiber or woodior some other equally goodainsulating material. The top and bottom cross rails 22 and 23 have the sheet. metal single` hoolred lengthwise flanges 26 and 27 inset lengthwise in'` their opposite inner edges. The top flange 2G is preferably made of two sheets of met-alplaced side by side andthe inner edge given a return bend to givethe proper single hooked forni desired. The edges 2S and 25) of the shee'tmetal spread apart and :i contact strip 30 is inserted there between with suitable insulationlfrom the edges 2S and 29. 4 tends the full lengt-h of the flange 2G' and ahnte the edges 2S .and 29 a sufficient dis-- :auw to insure a contact with` tlieh eddle 32.

The hcddlc 232 is preferably made of: Sheet stoel. though it may be made of wire and not depart from my invent-ion.

the iii-uitte for the thread 34;, the-ends of the hrfldlc 3.7 and 1G-are t-urnedi to oneside preferably in au angular return bend there'- l:\v fdrming The Contact strip 30 ek :i hook which lits "over the" A' threadl evti\ provided in the middle portion o.

imm amiga er .find 27. The lengt-'h o'f the heiidle 32 is pacedaccordingf to the hooked' flanges, 2t and 27 .so that thelhookedend 35 ill rest .firmlyY on the Contact stripBO'whenthe thread breaks, as shown in Fig. 3, the angular end insuring an electrical Contact and .stopping the loom. v

The heddle frame 2.1 is supported on the loom by means of hooks 37 and 38 in the top cross rail 3:2 and by hooks 39 and 4(1,in the bottom cross rail 23. i The electrical consaid enel piece within which thewire 42 is will be lowered nto the Contact strip 30 thus it. will be seen that the circuit will conplaced for connecting the hook 3T to the end of the Contact plate 3() without coming in Contact with theiipper edge 2l ot the metal lange L'.

'llie heilille traine is supported between the upper levers and the under levers 46 by means of wire links ll? and 47S, whit-li links eonneet the hooks 3T. and 3S, Si? and l0 to the insulating' links 49 and links 50' which connect to said levers 4.75 and 4G. A

-pair of contact pins 5l, and 52 are provided alongside each of the links 47 and :i eontaet wire 53 is pivotally attached to cacli ot said links 47 and given a turn around the pin 51. The ends of the contact wires K extend out beneath the pins 52 which pins are Connected bysiiitahle wire to the opposite poles of the battery or series of electrical supply 5:1, thereby Connecting the hooks 87 and 38 to the opposite polea of the ,battery 54.

.It is now apparent that when the heildle traine Q1 is raised and lowered by the levers 4,5 and 4G the connecting links will more upward and downward therewith including,` the links 47, thereby raising and lowering the ends of the contact wires 53 and making and breaking the electrical Contact with the pins 52 as the ends of the Contact wires 53 are. pressed against or move away from the pins 52 by said upward and downward movement of the heddle frame, The heddles 32 will be supported upon the threads 34 when the heddle is lowered thereby breaking the contact between the upper ends with the Contact strip BOj and when in this lowered posit-ion it is apparent that contact is made by the wires 53 on the pinsl AS the heddle frame li moves ii pwaril the wires 53 will be inoi'eo out ofcontact with the pins 52 andraimultaneously the lieddles 52 tiniie to remain broken either at. one nlace or thefother during the normal oi'ierai'ion of the loom with unbroken threads.

The operation of the different parts hasr been described when normally working with unbroken threads and it. is evident that the Llei-.trie circuit iniisl.- be continually disconnected' when the loom is running with iin- 'iirolieir threads',V for as soon afg the cire-uit is J closed the brake mecianisin will be operz4 'the lmn'k 3S has Contact.

I l with th(` upper (alge ll of tliimetal flange I breken ilireail would remain in contact, with z thereby if; re.

ated; thus when the thread breaks with the hedclie trame in the lowered position as shown in Vl ig. 2, the lieddle will immediately tall upon the Contact strip Si) thereby closing the electrical circuitand operating the brake mechanism and stopping the'looin. Should the heddle frame be in the raised position, as shown in Fig. 3, with the hed- -illes 'rl resting on the Contactl strip 30 and styles of looms is 'usually operated bynieans of a lever or crank and Shaft. A small tripping mechanism is shown by which to electrically operaie. thc lever or crank. A lever is shown in the draiifings here-with, but it is apparent that a shaftwith a crank or arm may-be turned in precisely the saine manner that the lever 55 is moved. Y

A crank arm or wheel 56 is attached to the crank shafty 57 of the loom and a .itnian titi, and a bar 58 is pivotally attac ed `to the pitnian 66 and slidably mounted on a second bar 59, which is supported in a,

bracketpiece. GG on the frame 20 of thelonni alongside the lever 55. The bar 59 extending' to within a Short distance of' the lever 55 to be 'pressed thereby against the, har 58 when the thread breaks in the fob f lowing manner; The bar 59 is pivotally mounted in the tripping plate G1 andend G2 of the tripping plate is made heavy, while the end G3 is made light, to normally bal` ance the tripping plate G1 downward at end (32 and ont et the way of' bar o8. Bar 58 has a tooth (34 mit t'i'iereon in close. prox` imity to the end 62 ot' the tripping plate (il so thatl as bar 58 is moved backward and forwardt as shown Ain dotted line in Fig. il, by means of the crank 56, the tootli (il will pass backward and forward over the end ('L of the trippingz plate G1. A magnet 65 is placed en the bracket. piece GO beneath the end 6ft of the tripping plate-'61,`

and when the thread breaks and the electricalcireiiit is thereby complete, as hereinbefore-.- described, the elefftrical current passes through the magnet thereby enr poweringthe magnet (35' to draw downward on the end (33 of the trippingr plate (5l` thereby tipping the end 62 upward into the path of the tooth G4 and is engaged thereby and causes the bar 59 to unite with the bar 5S in its reciprocating movement ng the bar 59 against. the

lever 55 and giving said lever the required l movement to operate the stopping mechanism of the loom.
